RedHat Security Advisory RHSA-2009:1536

Summary
The remote host is missing updates announced in advisory RHSA-2009:1536. Pidgin is an instant messaging program which can log in to multiple accounts on multiple instant messaging networks simultaneously. The AOL Open System for Communication in Realtime (OSCAR) protocol is used by the AOL ICQ and AIM instant messaging systems.

Refer to the Pidgin release notes for a full list of changes: http://developer.pidgin.im/wiki/ChangeLog All Pidgin users should upgrade to these updated packages, which correct this issue. Pidgin must be restarted for this update to take effect.
